|Sphere of Mysteries|
The Sphere of Mysteries, also known as the assassin's pyramid, was one of the twelve Spheres of Influence of the reconstituted Sith Empire. The Sphere was led by one of the twelve members of the Dark Council, and during the Great Galactic War the head of the Sphere was Darth Ekkage. Ekkage was famous for her command of the Red Legion, but she was captured during the war and imprisoned on Belsavis. During the Cold War, Darth Rictus was head of the Sphere, and his sphere of influence included the assassins of the Empire.
